Is there a Death Magic equivalent?

If not doesn't Spirit stealing seem like something that should be in the Death School rather than life?

I only ask as after seeing the spell while I was playing a Kingdom game, thinking thats not somethig my Goodly Soveriegn would do (didn't clock it was life magic at the time). I started a new game as an Empire race Custom Sov with the Roleplay intent of playing a Sovereign who would hoard his power by stealing the spirit of any magic using magelike champions (warriors with single magic spheres I already know get a pass). To my dismay no such spell that I can see anyway, leaving my planned mage Sov a master in Death magic with no means of branching out in other magics. Had I known I would of done things a lot differently. Enjoying the game so don't want to restart but thinking I may have to with no viable way of get my Sov more magic schools.
